The recent literature on embrittlement induced by solid or liquid metal environments is critically reviewed. Evidence in support of an enhanced shear model of embrittlement is provided for amorphous metals, while decohesion is shown to be a viable concept for crystalline metals. The usefulness of the concept of specificity of embrittlement is questioned on the basis of evidence for new embrittlement couples as the range of experimental conditions is varied. In particular, strain rate and temperture are shown to have extremely important effects on the degree of embrittlement. (Author).

The Corrosion Resistant Metals Committee and the Nuclear Metallurgy Committee of the Institute of Metals Division of The Metallurgical Society of AlME sponsored a 2-1/2 day symposium on "Corrosion by Liquid Metals". The symposium was held in Philadelphia, October 13-15, 1969, during the 1969 Fall Meeting of the Metallurgical Society and the Materials Engineering Con gress of the American Society for Metals. Cosponsors included the American Society for Metals and the American Nuclear Society. The purpose of the symposium was to bring together the several aspects of the subject of corrosion by liquid metals, so that perspective could be provided on the entire subject, to help in dividuals dealing with liquid metal corrosion problems acquire a sound basis of understanding, and to provide an opportunity for discussion between those doing research in this field. An exposition of the subject is timely, in view of the in creasing development of liquid metal heat and power sources for special purposes, including heat-pipe systems, NASA's SNAP power systems, and the AEC's liquid metal fast breeder reactor system. This book contains the proceedings of the symposium divided into four separate topics: I. Corrosion of Steels by Sodium, II. Alkali-Refractory Metal Interactions, III. Corrosion by Non-Alkali Metals, and IV. Analysis of Solid-Liquid Metal Inter actions (two sessions).

Many ductile metals in intimate contact with thin coatings of low melting solid metal which exhibit liquid metal embrittlement, also manifest severe embrittlement when tested at temperatures below the melting point of the coating. A significant decrease in stress, strain, and reduction-in-area occurs at fracture. Fracture propagates fast, but at a rate which is one or two orders of magnitude slower than that in liquid metal environments. Fracture occurs by brittle intergranular or transcrystalline mode with multiple cracks and branching. This new phenomena is known as solid metal induced embrittlement of metals (SMIE). SMIE also occurs when the embrittling metal is present as an internal environment in the base metal such as inclusions. This report describes the occurrence of SMIE in metals and alloys used in industry and presents results of recent investigations. It describes the effects of time, temperature, and stress on SMIE. It discusses the occurrence, the mechanisms of SMIE, and its similarity to LME. This new phenomena must be considered while investigating environmentally induced failure of failure analysis of metals and alloys.
